Yesterday, the coolant light was blinking while the engine was newly started from cold. Upon return from my trip, I checked the coolant level. It was right on the bottom of the expansion tank. I added some coolant - perhaps 2 cups - and so far things look fine.
I changed the expansion tank a couple years back. I do not smell coolant after long trips or in the trunk. But I understand the system is a closed loop.
So the 10,000 question is where did the coolant go?
The fear is a head gasket. But I have no evidence of that. Although I will obviously look for it now. Other ideas? I would hope for horses, not zebras.

BTW - my commute is exactly 8:02 - at least this AM. I know this because the opening strings of Stairway to Heaven began as I rolled out of the driveway and the end occurred just as I hit the bump stop of the parking space. As a result, my car does not always get close to operating temperature. I typically have several longish trips per month though. No idea if this is significant. Just noted.
